Abstract

Wood was used in the past in many industries in daily life,
including wooden coffins, in which many local woods were used.
These woods were affected by various damage factors such as
high temperatures and humidity, which led to the weakening of
these woods and made them vulnerable to the appearance of
various deterioration aspects.
Several consolidating materials were used to improve the
physical and mechanical properties, as the study sheds light on
the use of Klucel G, as it is one of the best materials used in the
recent consolidation of archaeological wooden objects, which
gave satisfactory results, klucel G concentration ,05 % and
Klucel G concentration 05 % with Nano paraloid concentration
1% by dissolving it in ethyl alcohol (ethanol), Visual assessment
and several analytical techniques were used for the evaluation of
the selected consolidate material . The analytical techniques are
Scanning Electron Microscope (SEM), Color change and
Measurement of physical Properties (Color Change CIE Lab,
Density, Porosity and Water Absorption) . The results obtained
from Color change revealed that Klucel G 0.5% gave the level
of total color differences (ΔE) KG1A and KG1AA with 2.38
and 1,69 respectively compared to the standard sample STA
gave 1.24 . The Density (g/cm3) to Klucel G 0.5% They are
(KG1A) and (KG1AA), which results in (0.443 g/cm3) and
(0.413 g/cm3), respectively, have the highest density compared
to the density of the rest of the samples of other materials and
compared to the standard sample STH (0.425 g/cm3).
